The U.S. transformer industry recorded values of USD 10.3 billion in 2022, USD 11.2 billion in 2023, and USD 12.2 billion in 2024. Market expansion is primarily fueled by increasing power infrastructure investments and the transition toward sustainable energy sources. The shift to renewable energy is a major factor in transformer demand, with renewable energy sources accounting for approximately 43% of total U.S. energy production in 2022. This transition places greater emphasis on modern transformers that can efficiently integrate variable renewable energy into the grid.
The shell core segment is expected to exceed USD 9 billion by 2034, experiencing strong growth due to the rising adoption of renewable energy systems. As the energy sector moves toward sustainable solutions, the need for advanced transformers capable of handling fluctuating loads and integrating renewables into the grid becomes critical.
The distribution transformer segment dominated the U.S. market in 2024, capturing over 69% of the total share. The segment is expected to expand further as industrialization and urban development drive electricity demand. The modernization of power distribution networks is accelerating, leading to increased deployment of energy-efficient transformers. Rising urban populations and expanding commercial infrastructure contribute to higher power consumption, requiring reliable and efficient power transmission solutions.
Innovations in transformer technology are reshaping the industry, particularly in the distribution segment. Advanced core materials are replacing traditional silicon steel cores, reducing energy losses caused by hysteresis and eddy currents. The aging infrastructure in the U.S. further accelerates the need for modern replacements. Industry estimates suggest that between 60 to 80 million distribution transformers are currently in use, with a capacity between 2.5 and 3.5 TVA. Notably, approximately 55% of these units have exceeded 33 years of service and are approaching the end of their operational life. Upgrading aging systems with modern, efficient transformers remains a key focus for sustaining grid reliability and optimizing energy use.
